IMPROVEMENT IN Cv-OPING- FOR WALLS.

i The Schedule referred to in these Letters Patent `and. making part of the same.

l To all whom it ma/y concern:

Be it known that I, JoHN Gnmnnon, of Albany,

in the county of Albany, and State of New Yorkhave invented a new and improved Cartabon/Coping for Walls; and I'do hereby declare that -thefollowing is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the' same, reference being had to the accompanying drawv ings forming part ot' this speciiication.

This invention relates to copings for walls, and consists in certain improvements on those jnow known to the public, which will be specified hereinafter.

Figure 1 is a transverse section of a wall provided Y withmy improved coping;`

Figure2 is a longitudinal section and Figure 3 isa side elevation ofthe same. l Similar let-ters of reference indicate 4correspomling parts.

A represents the coping-plates, made in sh ort sectious,

with downward-projecting `flanges B at each side,and with the transverse caps O at one end, and the transverse vertical fianges JE at the'other; also, with the short ilanges F at each side for connecting the ends of the sections together by bolts G. r

The vert-ical transverse flange and the cap C are to form a joint which will not admitY water and snow.4 lhe Ycap is made broad enough to allow for expansion and'gcontractin of the metal, andthe. space H between the ilange E and the wall I loi" the cap may be packed `wit-h ,elastic substancer\vhich willclose it, but will yield tothe changes of the metal. IThese copings may he iiat, oyal, or of other approved form on the "top,suitable for walls of any width, and cast in con-4 4venient lengths.

The flanges E extend across the top only, but the caps C extend down the sides as far as the tlangesl do, and the flanges F t against the sides of the wall and assist'to hold the copings, which are imbedded iu `mortaanpon thewalls more tirmly than would be the .case without them.

' When this coping comes in contact withchimneys or against a building higher than the wallon which they are, the chimney or wall may be built upon the 4iange E so as to project slightly, and make a watertight and permanent finish, the ends' to which the anges E are attached being always arranged against the saidwalls or chimneys.

These copings areintended asa substitute for the common wood copings, which are exposed to fire, also to decay by the action of the weather. They also -work loose by warping, vand admit the water, and disturb and break the top oi.' the wall by the movements 1 caused by warping ;y whereas these retain theirL places, are much more durable, and cost but a trifle more than thosemade of wood. They may also be more ornamental. Theyshould he coated with paint for i ,protectionV against corrosion.
